Road Weather Connected Vehicle Applications


Connected Vehicles

Presenter

Presentation Notes

Example variables that may be obtained from a vehicle


Connected Vehicle Data Translator(Pikalert® VDT)

• Software that creates highly detailed weather and road condition nowcasts and forecasts

• Inputs:– Vehicle-based measurements (vehicle actions, pavement

conditions, atmospheric measurements)– Traditional weather data sources

Image: NCAR

Presenter

Presentation Notes

How the VDT Works: Matches vehicle & weather data to road segments by GPS location and time stamp. Road segment length and update frequency are user configurable (default: 1-mile segments and 5-min update). Weather data are assigned to same road segments based on user-configured parameters such as distance to segment.


Using Pikalert VDT

Data is wirelessly transmitted from vehicles

Data is QC’d and processed

Road Weather Info. is

disseminated Road Weather Info. is fed into Decision Support Systems

Vehicle DataTranslator

Presenter

Presentation Notes

In this example, vehicle data are collected from a variety of providers. The data are QCh-ed and aggregated by the VDT into road segment statistics. End users can use these data to inform their own road weather applications and provide road weather content to users, such as through a 511 system or other content providers. The data only inform the applications. To get more end-user ready data, the VDT road segment statistics can be fed into the Pikalert Road Weather Hazard module, the EMDSS, and the MAW applications.


The Weather Data Environment (WDE)https://wxde.fhwa.dot.gov

• The WDE is a database system that collects, quality checks, archives, and disseminates road weather observations

• The purpose of WDE is to provide a data and interoperability platform to meet the weather-related research needs of the community, especially for ITS


WDE Functions • Collection of Data

– Road Weather Information Systems (RWIS)– Mobile Vehicles– Weather observations from the National Weather Service

(NWS) – used for quality checking– Metadata about the contributors, sites, stations, sensors,

observations, quality checks, and more

• Quality Checking of Observations (using Pikalert)• Dissemination of Data

– Map Graphical User Interface (GUI)– On-Demand Query– Subscription Service


WDE User Interface


Integrated Mobile Observations (IMO) Project

Objectives:• Better understand how to capture, communicate, and

process data from the vehicle’s internal codes and external road weather sensors placed on the vehicle

• Identify uses for and incorporation of the data in new and established applications

• Evaluate the impacts and results of utilizing the data in applications

Outcomes:• Used to enhance decision making by traffic operators,

maintenance managers, and travelers


Integrated Mobile Observations (IMO) Project

Minnesota DOT• ~550 Vehicles• Data

Presenter

Presentation Notes

The Goal focuses on improving safety and mobility with respect to weather Objectives: Better understand how to capture, communicate, and process data from the vehicles’ internal codes and external road weather sensors placed on the vehicle Identify uses for and incorporation of the data in new and established applications Assess the impact and results of utilizing the data in the applications In all cases, they automated the collection of and dissemination of Road Weather Mobile Observations


Enhanced Maintenance Decision Support System (EMDSS)

• Produces road weather forecasts and winter maintenance treatment recommendations

• Aids maintenance managers and other personnel in key decisions of treatment type, timing, rates, and locations

• The plow truck becomes a connected vehicle.

Presenter

Presentation Notes

EMDSS is a maintenance-specific application. For a traveler information application, see the MAW section


EMDSS Display – Vehicle Locations, Radar, Road Segment Trouble Areas


Motorist Advisory and Warning (MAW) System

• Displays road weather alerts and hazard forecasts to decision makers ranging from DOT personnel to the traveling public

• Uses VDT output and road weather forecasts to provide these alerts

• Pre-trip: web-based display • En-route: mobile application


MAW Web-based Display


MAW Mobile Application

20SICOP Meeting - July 16,2016 – Las Vegas, NV

Weather Responsive Traffic Management• Wyoming DOT

– Road condition reporting app on tablets– Installed on plow trucks– Data electronically sent to TMC– VSL and DMS are adjusted

• South Dakota DOT– Combined IRIS/MDC road reporting

and MDSS forecasting– Enhanced content and display of

severe weather advisories– Website, mobile app and 511 alert travelers

• Michigan DOT– Combined fixed and mobile obs– Quality checking and analysis– Conditions and forecasts used in

ATMS, DMS and website

Presenter

Presentation Notes

We completed, evaluated and documented 3 WRTM implementation projects with 3 State DOT’s. The systems developed utilized mobile observations from vehicles, including manual and automatically collected sensing data, for a variety of traffic management purposes including VSL, DMS, website and mobile apps. The systems and data are not only useful for traffic management but also winter maintenance operations, for example the road weather forecasts can be used to schedule and allocate winter maintenance activities and resources.


Smarter Work Zones:an EDC-3 Initiative


EDC-3 Smarter Work Zone Initiative

Deployment of ITS for dynamic management of work zone traffic impacts, such as queue and speed management

22

Project Coordination

Coordination within a single project and/or among multiple projects within a corridor, network, or region, and possibly across agency jurisdictions

Innovative strategies designed to optimize work zone safety and mobility

Technology Application

Presenter

Presentation Notes

Here are the two SWZ initiatives that we will focus on for implementation under EDC-3 PC TA We will discuss these in more detail after this introduction segment of the presentation.


Project Coordination Strategy Examples

• Region or corridor-wide software for ROW construction activity coordination

• Corridor-level Traffic Management Plans (TMPs) to address traffic-related construction impacts

• Corridor-level thresholds to minimize work zone mobility impacts

• Multi-agency construction traffic management activities

Project Coordination Tool Work Zone Implementation Strategies Estimator (WISE)

24

• Developed under the SHRP2 R11 project• Made up of two modules (planning and operations)• Proactively reduces WZ impacts by:

Effective project coordination upfront in planning/programming Carrying coordination through to project planning/design decisions

• Four organizations awarded grants to pilot the WISE tool California – Assoc. of Monterey Bay Area Governments MPO Florida – MetroPlan Orlando MPO Maryland DOT Tennessee DOT

Presentation Notes

Here we are discussing a new software tool developed under SHRP2 R11 project Help assess sequencing of renewal projects and determine strategies to minimize, manage, and mitigate road user costs in terms of safety and operation It has 2 Modules: - Planning Module provides an optimized renewal programming schedule that minimizes delays to the public and agency cost Operations Module uses DynusT, mesoscopic simulation tool, platform that evaluates the impact of individual strategies at the project level to minimize RUC Results from planning module are transferred internally to operations module – similarly results from operations module can be used as part of an iterative procedure with the planning analysis Audience: - DOT Program Managers in moderately and densely urbanized States, experiencing congestion, and with an active Renewal program - Planners and Program Managers in moderate and large MPOs, with an active Renewal program Validation sites: Des Moines, IA Phoenix, AZ Pilot sites: Orlando, FL Worcester, MA Tool and documentation is available on TRB web sit SHRP2 implementation: IPW expected in December More resources such as case studies and training should be available through that effort **** Here we are discussing a new software tool developed under SHRP2 R11 project. The WISE tool is a decision support system that helps evaluate the impact of work zones and determine strategies to reduce these impacts Made up of two modules and we will go into each module more in the upcoming slides.
